Colombia’s Decree on the Control of Firearms, Ammunition and Explosives (1993) states that firearms which have undergone substantial modification in manufacture or origin to make them more deadly are prohibited.

In 2006, in the Constitutional Case No. T-165/06, the First Appeals Chamber of Colombia’s Constitutional Court stated:

[The principles of distinction, limitation and proportionality] are found throughout IHL. Regarding the protection of victims in international or non-international armed conflicts, they materialize in concrete rules, such as … [the one] that: prohibits the use of weapons, projectiles, material and methods of warfare of a nature to cause superfluous or unnecessary suffering.

In 1975, during discussions in the Ad Hoc Committee on Conventional Weapons established by the CDDH, the representative of Colombia stated:

8. … His government … supported all measures for the prohibition or limitation of the use of conventional weapons likely to cause unnecessary injury …

9. … His Government was opposed to the use of napalm and incendiary weapons. In view of the suffering inflicted on the victims, nothing could justify their use. Similarly, the use of high velocity small-calibre projectiles designed to cause excessive injury should be absolutely forbidden. Such weapons were indeed comparable to explosive bullets or dum-dum bullets.

In 1977, during a debate in the First Committee of the UN General Assembly, Colombia advocated the elimination of “weapons of mass destruction, chemical and bacteriological weapons, incendiary weapons and all those weapons that are capable of bringing about the most horrifying suffering”.
